From: Ronnie Sahlberg <sahlberg@xxxxxxxxxx>
Change lock_ref_sha1_basic to return an error instead of dying,
when we fail to lock a file during a transaction. This function is
only called from transaction_commit() and it knows how to handle
these failures.
[sb: This was part of a larger patch series, cherry-picked to master]
